Requirements for flux repo CLI tool

[aanthony1243]

Notes:

1. have flux delivered as a CLI named that with no dependency on InfluxDB.
2. brew installable/go gettable.
3. The Flux command should support all the from types.
4. For InfluxDB there should be a from that uses the HTTP interface (the 2.0 one). So it would only work against 1.7 or higher
5. Ideally, all the RPC logic can be extracted into a library that can just be used by flux, the influx CLI or anything else. We’ll want more complicated logic over time for each of the from sources

Thanks Adam - for [2] - let's change that from nice-to-have to a requirement? We don't need to build the brew recipe now .. but for sure it needs to be go-gettable. We can assume that we are in the future and can rely on go module support everywhere.
